General Description
ATS477 that integrates Hall sensor with output
drivers is designed for electrical commutation of
brush-less DC motor application. The device
includes
on-chip
Hall
voltage
generator
for
magnetic sensing, the error amplifier that amplifies
the Hall voltage, a comparator that is to provide
switching hysteresis for noise rejection, the
bi-direction drivers for sinking and driving large
current load, and the frequency generator (FG) that
provides a signal proportional to rotation speed.
Internal bandgap regulator is used to provide
temperature compensated bias for internal circuits
and allows a wide operating supply voltage range.
Built-in protection circuit and output shunt Zener
diodes were applied for protecting output drivers
during operating.
If a magnetic flux density is larger than threshold
Bop, DO is turned to sink and DOB is turned to
drive. The output state is held until a magnetic flux
density reversal falls below Brp causing DO to be
turned to drive and DOB turned to sink.
ATS477 is rated for operation over-temperature
range from -20
oC to 85 oC and voltage range from
3.5V to 20V. The devices are available in low cost
die forms or rugged SIP-4L and power SOP-7L
packages.
